The name also retains an oblique reference to Eris's old informal name Xena, portrayed on television by <a href="/wiki/Lucy_Lawless" title="Lucy Lawless">Lucy Lawless</a>, though the connection was unintentional.<a href="#cite_note-Tytell-ST2006-89">[82]</a> <table class="wikitable"> <caption>Eridian system </caption> <tbody><tr> <th>Name </th> <th>Diameter (km) </th> <th>Semi-major axis (km) </th> <th>Mass (× 1022 kg) </th> <th>Discovery date </th></tr> <tr> <td>Eris </td> <td>2326±12<a href="#cite_note-sicardy-12">[12]</a> </td> <td> </td> <td>1.638±0.014<a href="#cite_note-erismass-16">[b]</a> </td> <td>January 5, 2005 </td></tr> <tr> <td>Dysnomia </td> <td>615+60 −50<a href="#cite_note-Brown2023-90">[83]</a> </td> <td>37273±64<a href="#cite_note-Holler2021-15">[14]</a> </td> <td>0.008±0.006<a href="#cite_note-Brown2023-90">[83]</a> </td> <td>September 10, 2005<a href="#cite_note-Brown_Van_Dam_et_al._2006-88">[81]</a> </td></tr></tbody></table> <div class="mw-heading mw-heading2"><h2 id="Exploration">Exploration</h2>[<a href="/w/index.php?title=Eris_(dwarf_planet)&action=edit&section=11" title="Edit section: Exploration">edit</a>]</div> Eris was observed from afar by the outbound <a href="/wiki/New_Horizons" title="New Horizons">New Horizons</a> spacecraft in May 2020, as part of its extended mission following its successful Pluto <a href="/wiki/Flyby_(spaceflight)" title="Flyby (spaceflight)">flyby</a> in 2015.<a href="#cite_note-Verbiscer2022-22">[17]</a> Although Eris was farther from New Horizons (112 AU) than it was from Earth (96 AU), the spacecraft's unique vantage point inside the Kuiper belt permitted observations of Eris at high <a href="/wiki/Phase_angle_(astronomy)" title="Phase angle (astronomy)">phase angles</a> that are otherwise unobtainable from Earth, enabling the determination of the light scattering properties and <a href="/wiki/Phase_curve_(astronomy)" title="Phase curve (astronomy)">phase curve</a> behavior of the Eridian surface.<a href="#cite_note-Verbiscer2022-22">[17]</a> In the 2010s, there were multiple studies for follow-on missions to explore the Kuiper belt, among which Eris was evaluated as a candidate.<a href="#cite_note-91">[84]</a> It was calculated that a flyby mission to Eris would take 24.66 years using a Jupiter gravity-assist, based on launch dates of April 3, 2032, or April 7, 2044.
